+Ruby4Knime is a realization of special node types for
+http://knime.org that allow to use Ruby scripts for
+interactive data analytic.
+
 The main aims of this project are:
 * provide possibility to use Ruby language for interactive data analysis;
 * make the analysis more effective using clear and laconic Ruby style.
 
-knime.rb is the simple mediator that allows to use KNIME`s classes written in Java in the Ruby programming style and also use all Java classes without any changes.

 == Copy existing rows
 
-  $inData0.each do |row|
-    $outContainer << row

+    $out_data_0 << row
   end
 
 == Add new two columns with String and Int types
 This example also illustrates the progress state updating.
 
-  count = $inData0.length
-  $inData0.each_with_index do |row, i|

+
     setProgress "#{i*100/count}%" if i%100 != 0
   end
 
 == Create new rows
-In this example new rows creates with new uniq rowkeys. Therefore it is possible to create output table with any number of rows.
-  $inData0.each do |row|
-    $outContainer << Cells.new.string(row.getCell(0).to_s.length.to_s)

-In this example cell 0 copies without changes and adds difference between cells with indexes 1 and 2. Index in Ruby style.
-  $inData0.each do |row|
-    $outContainer << Cells.new.int(row[0].to_i).double(row[1].to_f - row[2].to_f)

 = Other notes
 
 Now it is possible to use any types of KNIME in the DataOutput table.
 Simply input a full qualified Java class name in the configuration dialog of
-the Ruby node. E.g. org.knime.core.data.def.ComplexNumberCell or 
-org.knime.ext.textprocessing.data.DocumentCell.
